Improved Frequency Measurement of the ^sup 1^S^sub 0^-^sup 3^P^sub 0^ Clock Transition in ^sup 87^Sr Using a Cs Fountain Clock as a Transfer Oscillator

We performed an absolute frequency measurement of the ...S...-...P... transition in ...Sr with a fractional uncertainty of 1.2 x 10..., which is less than one-third that of our previous measurement.

Zusammenfassung:We performed an absolute frequency measurement of the ...S...-...P... transition in ...Sr with a fractional uncertainty of 1.2 x 10..., which is less than one-third that of our previous measurement. A caesium fountain atomic clock was used as a transfer oscillator to reduce the uncertainty of the link between a strontium optical lattice clock and the SI second. The absolute value of the transition frequency is 429 228 004 229 873.56(49) Hz. (ProQuest: ... denotes formulae/symbols omitted.)
